The Shark IQ 2 in 1 has exceeded all expectations! I didn’t think it would work as well as it has. This unit has picked up all the cat hair quickly and easily. We have wood, carpet and tile flooring. It has worked spectacularly on each. 
The wet mopping function is amazing too. The set up was super easy and the app functionality is easy to navigate. It is a smart device that avoids obstacles and stops automatically at the steps. 
This has made our lives so much easier. I wish we would have gotten one earlier. 10/10 recommend.
